Contingent Income Auto-Callable Securities due June 16, 2022

All Payments on the Securities Based on the Worst Performing of the Russell 2000^® Index, the EURO STOXX 50^® Index and the MSCI Emerging Markets Index
Principal at Risk Securities

Contingent Income Auto-Callable Securities do not guarantee the payment of interest or the repayment of principal.  Instead, the securities offer the opportunity for investors to earn a contingent quarterly payment equal to 2.25% of the stated principal amount, but only with respect to each determination date on which the closing level of each of the Russell 2000^® Index, the EURO STOXX 50^® Index and the MSCI Emerging Markets Index is greater than or equal to 75% of its initial index value, which we refer to as a coupon barrier level.  If, however, on any determination date, the closing level of any underlying index is less than its coupon barrier level, you will not receive any contingent quarterly payment for the related quarterly period.  In addition, if the closing level of each underlying index is greater than or equal to its initial index value on any determination date (other than the final determination date), the securities will be automatically redeemed for an amount per security equal to the stated principal amount and the contingent quarterly payment.  If the securities have not been automatically redeemed prior to maturity and the final index value of each underlying index is greater than or equal to 55% of its initial index value, which we refer to as a downside threshold level, the payment at maturity due on the securities will be the stated principal amount and, if the final index value of each underlying index is also greater than or equal to its coupon barrier level, the contingent quarterly payment with respect to the final determination date.  If, however, the final index value of any underlying index is less than its downside threshold level, you will be exposed to the decline in the worst performing underlying index, as compared to its initial index value, on a 1-to-1 basis and will receive a payment at maturity that is less than 55% of the stated principal amount of the securities and could be zero.  The securities are for investors who are willing to risk their principal and seek an opportunity to earn interest at a potentially above-market rate in exchange for the risk of receiving few or no contingent quarterly payments and also the risk of receiving a payment at maturity that will be significantly less than the stated principal amount of the securities and could be zero.  Accordingly, investors could lose their entire initial investment in the securities.  Because all payments on the securities are based on the worst performing of the underlying indices, (i) a decline of any underlying index beyond its coupon barrier level will result in few or no contingent quarterly payments and (ii) a decline of any underlying index beyond its downside threshold level will result in a significant loss of your initial investment, even if, in each case, the other underlying indices appreciate or have not declined as much.  Investors will not participate in any appreciation of any underlying index. The securities are unsecured and unsubordinated obligations of JPMorgan Chase & Co., issued as part of JPMorgan Chase & Co.’s Medium-Term Notes, Series E, program.  Any payment on the securities is subject to the credit risk of JPMorgan Chase & Co.

Principal at Risk Securities

Investment Summary

The Contingent Income Auto-Callable Securities due June 16, 2022 Based on the Worst Performing of the Russell 2000^® Index, the EURO STOXX 50^® Index and the MSCI Emerging Markets Index, which we refer to as the securities, do not provide for the regular payment of interest. Instead, the securities provide an opportunity for investors to earn a contingent quarterly payment, which is an amount equal to $0.225 (2.25% of the stated principal amount) per security, with respect to each quarterly determination date on which the closing level of each underlying index is greater than or equal to 75% of its initial index value, which we refer to as a coupon barrier level. The contingent quarterly payment, if any, will be payable quarterly on the relevant contingent payment date, which is the third business day after the related determination date or, in the case of the contingent quarterly payment, if any, with respect to the final determination date, the maturity date. If the closing level of any underlying index is less than its coupon barrier level on any determination date, investors will receive no contingent quarterly payment for the related quarterly period. It is possible that the closing level of each underlying index could remain below its coupon barrier level for extended periods of time or even throughout the term of the securities so that you will receive few or no contingent quarterly payments during the term of the securities. We refer to these payments as contingent, because there is no guarantee that you will receive a payment on any contingent payment date. Even if all of the underlying indices were to be at or above their respective coupon barrier levels on some quarterly determination dates, one or all underlying indices may fluctuate below their respective coupon barrier level(s) on others.

If the closing level of each underlying index is greater than or equal to its initial closing value on any determination date (other than the final determination date), the securities will be automatically redeemed for an early redemption payment equal to the stated principal amount plus the contingent quarterly payment with respect to the related determination date. If the securities have not previously been redeemed and the final index value of each underlying index is greater than or equal to its downside threshold level, the payment at maturity will be the sum of the stated principal amount and, if the final closing value of each underlying index is also greater than or equal to its coupon barrier level, the contingent quarterly payment with respect to the final determination date. However, if the securities have not been automatically redeemed prior to maturity and the final index value of any underlying index is less than its downside threshold level, investors will be exposed to the decline in the worst performing underlying index, as compared to its initial index value, on a 1-to-1 basis and will receive a payment at maturity that is less than 55% of the stated principal amount of the securities and could be zero. Accordingly, investors in the securities must be willing to accept the risk of losing their entire initial investment and also the risk of receiving few or no contingent quarterly payments during the term of the securities. In addition, investors will not participate in any appreciation of the underlying indices.

Supplemental Terms of the Securities

For purposes of the accompanying product supplement, each underlying index is an “Index.”

Principal at Risk Securities

Key Investment Rationale

The securities do not provide for the regular payment of interest. Instead, the securities offer investors an opportunity to earn a contingent quarterly payment equal to 2.25% of the stated principal amount with respect to each determination date on which the closing level of each underlying index is greater than or equal to 75% of its initial index level, which we refer to as a coupon barrier level. The securities may be redeemed prior to maturity for the stated principal amount per security plus the applicable contingent quarterly payment, and the payment at maturity will vary depending on the final index value of each underlying index, as follows:

Scenario 1	This scenario assumes that, prior to early redemption, each underlying index closes at or above its coupon barrier level on some determination dates but one or all of the underlying indices closes below their respective coupon barrier levels on the others. On the 18th determination date, the closing level of each underlying index is greater than or equal to its initial index value. Investors receive the contingent quarterly payment for the quarterly periods in which the closing level of each underlying index is at or above its coupon barrier level on the related determination date. On the contingent payment date immediately following the 18th determination date, the securities will be automatically redeemed for the stated principal amount plus the contingent quarterly payment with respect to the related determination date.
Scenario 2	This scenario assumes that each underlying index closes at or above its coupon barrier level on some determination dates but one or all of the underlying indices closes below their respective coupon barrier levels on the others, and each underlying index closes below its initial index value on all the determination dates prior to the final determination date. On the final determination date, each underlying index closes at or above its downside threshold level. Consequently, the securities are not automatically redeemed, and investors receive a contingent quarterly payment for the quarterly periods in which the closing level of each underlying index is at or above its coupon barrier level on the related determination date. At maturity, investors will receive the stated principal amount and, if each final index value is greater than or equal to its coupon barrier level, the contingent quarterly payment with respect to the final determination date.
Scenario 3	This scenario assumes that each underlying index closes at or above its coupon barrier level on some determination dates but one or all of the underlying indices closes below their respective coupon barrier levels on the others, and each underlying index closes below its initial index value on all the determination dates prior to the final determination date. On the final determination date, one or all of the underlying indices close below their downside threshold levels. Consequently, the securities are not automatically redeemed, and investors receive a contingent quarterly payment for the quarterly periods in which the closing level of each underlying index is at or above its coupon barrier level on the related determination date. At maturity, investors will receive the stated principal amount times the index performance factor of the worst performing underlying index, which will be less than 55% of the stated principal amount and could be zero. Investors will lose some and may lose all of their principal in this scenario.

Hypothetical Examples

The following hypothetical examples illustrate how to determine whether a contingent quarterly payment is payable with respect to a determination date, whether the securities will be automatically redeemed on any determination date prior to the final determination date and how to calculate the payment at maturity if the securities have not been redeemed early. The following examples are for illustrative purposes only. Whether you receive a contingent quarterly payment or whether the securities will be automatically redeemed will be determined by reference to the closing level of each underlying index on each quarterly determination date and the amount you will receive at maturity, if any, will be determined by reference to the final index value of each underlying index. All payments on the securities, if any, are subject to the credit risk of JPMorgan Chase & Co. The numbers in the hypothetical examples below may have been rounded for the ease of analysis. The examples below are based on the following assumed terms:

Contingent quarterly payment:	A contingent quarterly payment of $0.225 per quarter per security will be paid on the securities on each contingent payment date but only if the closing level of each underlying index is at or above its coupon barrier level on the related determination date.
Early redemption:	If the closing level of each underlying index is greater than or equal to its initial index value on any quarterly determination date (other than the final determination date), the securities will be automatically redeemed for an early redemption payment equal to the stated principal amount plus the contingent quarterly payment with respect to the related determination date.
Payment at maturity (if the securities have not been automatically redeemed early):	If the final index value of each underlying index is greater than or equal to its downside threshold level: the stated principal amount and, if the final index value of each underlying index is also greater than or equal to its coupon barrier level, the contingent quarterly payment with respect to the final determination date If the final index value of any underlying index is less than its downside threshold level: (i) the stated principal amount times (ii) the index performance factor of the worst performing underlying index
Stated principal amount:	$10 per security
Hypothetical initial index value:	With respect to the RTY Index: 1,250.00 With respect to the SX5E Index: 3,600.00 With respect to the MXEF Index: 1,000.00
Hypothetical coupon barrier level:	With respect to the RTY Index: 937.50, which is 75% of the hypothetical initial index value for such index With respect to the SX5E Index: 2,700.00, which is 75% of the hypothetical initial index value for such index With respect to the MXEF Index: 750.00, which is 75% of the hypothetical initial index value for such index
Hypothetical downside threshold level:	With respect to the RTY Index: 687.50, which is 55% of the hypothetical initial index value for such index With respect to the SX5E Index: 1,980.00, which is 55% of the hypothetical initial index value for such index With respect to the MXEF Index: 550.00, which is 55% of the hypothetical initial index value for such index

How to determine whether a contingent quarterly payment is payable with respect to a determination date:

	Closing level			Contingent quarterly payment
	RTY Index	SX5E Index	MXEF Index
Hypothetical Determination Date 1	1,200 (at or above coupon barrier level)	3,500 (at or above coupon barrier level)	900 (at or above coupon barrier level)	$0.225
Hypothetical Determination Date 2	850 (below coupon barrier level)	3,000 (at or above coupon barrier level)	600 (below coupon barrier level)	$0
Hypothetical Determination Date 3	1,050 (at or above coupon barrier level)	2,000 (below coupon barrier level)	650 (below coupon barrier level)	$0
Hypothetical Determination Date 4	800 (below coupon barrier level)	2,500 (below coupon barrier level)	600 (below coupon barrier level)	$0

On hypothetical determination date 1, each underlying index closes at or above its coupon barrier level. Therefore, a contingent quarterly payment of $0.225 is payable on the relevant contingent payment date.

On each of the hypothetical determination dates 2 and 3, one underlying index closes at or above its coupon barrier level but the other underlying indices close below their respective coupon barrier levels. Therefore, no contingent quarterly payment is payable on the relevant contingent payment date.

On hypothetical determination date 4, each underlying index closes below its coupon barrier level and, accordingly, no contingent quarterly payment is payable on the relevant contingent payment date.

You will not receive a contingent quarterly payment on any contingent payment date if the closing level of any underlying index is below its coupon barrier level on the related determination date.

How to determine whether the securities will be automatically redeemed on any determination date prior to the final determination date:

	Closing level			Early Redemption Payment
	RTY Index	SX5E Index	MXEF Index
Hypothetical Determination Date 1	1,400 (at or above initial index value)	3,000 (below initial index value)	900 (below initial index value)	n/a (securities are not redeemed early)
Hypothetical Determination Date 2	800 (below initial index value)	3,000 (below initial index value)	850 (below initial index value)	n/a (securities are not redeemed early)
Hypothetical Determination Date 3	1,350 (at or above initial index value)	3,700 (at or above initial index value)	1,100 (at or above initial index value)	$10.225 (the stated principal amount plus the contingent quarterly payment with respect to the related determination date)

On hypothetical determination date 1, one underlying index closes at or above its initial index value but the other underlying indices close below their respective initial index values. Therefore, the securities remain outstanding and are not redeemed early.

On hypothetical determination date 2, each underlying index closes below its initial index value. Therefore, the securities remain outstanding and are not redeemed early.

On hypothetical determination date 3, each underlying index closes at or above its initial index value. Therefore, the securities are automatically redeemed and you receive an early redemption payment equal to the stated principal amount plus the contingent quarterly payment with respect to the related determination date. No further payments will be made on the securities once they have been redeemed.

How to calculate the payment at maturity (if the securities have not been automatically redeemed early):

	Final Index Value			Payment at Maturity
	RTY Index	SX5E Index	MXEF Index
Example 1:	1,300 (at or above downside threshold level and coupon barrier level)	2,800 (at or above downside threshold level and coupon barrier level)	900 (at or above downside threshold level and coupon barrier level)	$10.225 (the stated principal amount plus the contingent quarterly payment with respect to the final determination date)
Example 2:	1,300 (at or above downside threshold level and coupon barrier level)	2,100 (at or above downside threshold level; below coupon barrier level)	650 (at or above downside threshold level; below coupon barrier level)	$10.00 (the stated principal amount)
Example 3:	500 (below downside threshold level)	2,800 (at or above downside threshold level)	450 (below downside threshold level)	$10 × index performance factor of the worst performing underlying index = $10 × (500 / 1,250) = $4.00
Example 4:	1,250 (at or above downside threshold level)	1,800 (below downside threshold level)	525 (below downside threshold level)	$10 × (1,800 / 3,600) = $5.00
Example 5:	600 (below downside threshold level)	1,440 (below downside threshold level)	450 (below downside threshold level)	$10 × (1,440 / 3,600) = $4.00
Example 6:	375 (below downside threshold level)	1,400 (below downside threshold level)	400 (below downside threshold level)	$10 × (375 / 1,250) = $3.00

In example 1, the final index value of each underlying index is at or above its downside threshold level and coupon barrier level. Therefore, you receive at maturity the stated principal amount of the securities and the contingent quarterly payment with respect to the final determination date.

In example 2, the final index value of each underlying index is at or above its downside threshold level and the final index value of one underlying index is at or above its coupon barrier level, but the final index values of the other underlying indices are below their respective coupon barrier levels. Therefore, you receive at maturity only the stated principal amount of the securities.

In examples 3 and 4, the final index value of one underlying index is at or above its downside threshold level but the final index values of the other underlying indices are below their respective downside threshold levels. Therefore, you are exposed to the downside performance of the worst performing underlying index at maturity and receive at maturity an amount equal to the stated principal amount times the index performance factor of the worst performing underlying index.

Similarly, in examples 5 and 6, the final index value of each underlying index is below its downside threshold level, and you receive at maturity an amount equal to the stated principal amount times the index performance factor of the worst performing underlying index.

If the final index value of ANY underlying index is below its downside threshold level, you will be exposed to the downside performance of the worst performing underlying index at maturity, and your payment at maturity will be less than 55% of the stated principal amount per security and could be zero.

Risk Factors

The following is a non-exhaustive list of certain key risk factors for investors in the securities. For further discussion of these and other risks, you should read the sections entitled “Risk Factors” beginning on page PS-8 of the accompanying product supplement no. 4a-I and “Risk Factors” beginning on page US-2 of the accompanying underlying supplement no. 1a-I. We urge you to consult your investment, legal, tax, accounting and other advisers in connection with your investment in the securities.

§ The securities do not guarantee the return of any principal and your investment in the securities may result in a loss. The terms of the securities differ from those of ordinary debt securities in that the securities do not guarantee the payment of regular interest or the return of any of the principal amount at maturity. Instead, if the securities have not been automatically redeemed prior to maturity and if the final index value of any of the underlying indices is less than its downside threshold level, you will be exposed to the decline in the closing level of the worst performing underlying index, as compared to its initial index value, on a 1-to-1 basis and you will receive for each security that you hold at maturity an amount equal to the stated principal amount times the index performance factor of the worst performing underlying index. In this case, your payment at maturity will be less than 55% of the stated principal amount and could be zero.

§ The securities do not provide for the regular payment of interest. The terms of the securities differ from those of ordinary debt securities in that they do not provide for the regular payment of interest. Instead, the securities will pay a contingent quarterly payment but only if the closing level of each underlying index is at or above its coupon barrier level on the related determination date. If, on the other hand, the closing value of any underlying index is lower than its coupon barrier level on the relevant determination date, we will pay no payment on the applicable contingent payment date. It is possible that the closing level of any underlying index could remain below its coupon barrier level for extended periods of time or even throughout the entire term of the securities so that you will receive few or no contingent quarterly payments. If you do not earn sufficient contingent payments over the term of the securities, the overall return on the securities may be less than the amount that would be paid on a conventional debt security of the issuer of comparable maturity.

§ You are exposed to the price risk of all three underlying indices, with respect to all the contingent quarterly payments, if any, and the payment at maturity, if any. Your return on the securities is not linked to a basket consisting of the underlying indices. Rather, it will be contingent upon the independent performance of each underlying index. Unlike an instrument with a return linked to a basket of underlying assets in which risk is mitigated and diversified among all the components of the basket, you will be exposed to the risks related to each underlying index. The performance of the underlying indices may not be correlated. Poor performance by any underlying index over the term of the securities may negatively affect your return and will not be offset or mitigated by any positive performance by the other underlying indices. Accordingly, your investment is subject to the risk of decline in the closing level of each underlying index.

To receive any contingent quarterly payments, each underlying index must close at or above its coupon barrier level on the applicable determination date. In addition, if any underlying index has declined to below its downside threshold level as of the final determination date, you will be fully exposed to the decline in the worst performing underlying index, as compared to its initial index value, on a 1-to-1 basis, even if the other underlying indices have appreciated. Under this scenario, the value of any such payment will be less than 55% of the stated principal amount and could be zero.

§ Because the securities are linked to the performance of the worst performing underlying index, you are exposed to greater risks of no contingent quarterly payments and sustaining a significant loss on your investment than if the securities were linked to just one underlying index. The risk that you will not receive any contingent quarterly payments, or that you will suffer a significant loss on your investment is greater if you invest in the securities than if you invest in substantially similar securities that are linked to the performance of just one underlying index. With three underlying indices, it is more likely that any underlying index will close below its coupon barrier level on any determination date or its downside threshold level on the final determination date than if the securities were linked to only one underlying index. In addition, you will not benefit from the performance of any underlying index other than the worst performing underlying index. Therefore it is more likely that you will not receive any contingent quarterly payments and that you will suffer a significant loss on your investment.

§ The contingent quarterly payment is based solely on the closing level of the underlying indices on the specified determination dates. Whether the contingent quarterly payment will be made with respect to a determination date will be based on the closing level of each underlying index on that determination date. As a result, you will not know whether you will receive the contingent quarterly payment until the related determination date. Moreover, because the contingent quarterly payment is based solely on the closing level of each underlying index on quarterly determination dates, if the closing level of any of the underlying indices on any determination date

Principal at Risk Securities

is below its coupon barrier level, you will not receive any contingent quarterly payment with respect to that determination date, even if the closing level of that underlying index was higher on other days during the related quarterly period.

§ You will not receive any contingent quarterly payment for any quarterly period where the closing level of any underlying index on the relevant determination date is less than its coupon barrier level. A contingent quarterly payment will be made with respect to a quarterly period only if the closing level of each underlying index on the relevant determination date is greater than or equal to its coupon barrier level. If the closing level of any underlying index remains below its coupon barrier level on each determination date over the term of the securities, you will not receive any contingent quarterly payment.

§ The securities are subject to the credit risk of JPMorgan Chase & Co., and any actual or anticipated changes to our credit ratings or credit spreads may adversely affect the market value of the securities. Investors are dependent on JPMorgan Chase & Co.’s ability to pay all amounts due on the securities. Any actual or anticipated decline in our credit ratings or increase in the credit spreads determined by the market for taking our credit risk is likely to adversely affect the market value of the securities. If we were to default on our payment obligations, you may not receive any amounts owed to you under the securities and you could lose your entire investment.

§ Investors will not participate in any appreciation in any underlying index. Investors will not participate in any appreciation in any underlying index from its initial index value, and the return on the securities will be limited to the contingent quarterly payment that is paid with respect to each determination date on which the closing level of each underlying index is greater than or equal to its coupon barrier level, if any.

§ An investment in the securities is subject to risks associated with small capitalization stocks with respect to the RTY Index. The stocks that constitute the RTY Index are issued by companies with relatively small market capitalization. The stock prices of smaller companies may be more volatile than stock prices of large capitalization companies. Small capitalization companies may be less able to withstand adverse economic, market, trade and competitive conditions relative to larger companies. Small capitalization companies are less likely to pay dividends on their stocks, and the presence of a dividend payment could be a factor that limits downward stock price pressure under adverse market conditions.

§ The securities are subject to risks associated with securities issued by non-U.S. companies, with respect to the SX5E Index and the MXEF Index. The equity securities included in the SX5E Index and the MXEF Index have been issued by non-U.S. companies. Investments in securities linked to the value of such non-U.S. equity securities involve risks associated with the securities markets in the home countries of the issuers of those non-U.S. equity securities, including risks of volatility in those markets, governmental intervention in those markets and cross shareholdings in companies in certain countries. Also, there is generally less publicly available information about companies in some of these jurisdictions than there is about U.S. companies that are subject to the reporting requirements of the SEC, and generally non-U.S. companies are subject to accounting, auditing and financial reporting standards and requirements and securities trading rules different from those applicable to U.S. reporting companies.

§ The securities are subject to risks associated with emerging markets with respect to the MXEF Index.The equity securities included in the MXEF Index have been issued by non-U.S. companies located in emerging markets countries. Countries with emerging markets may have relatively unstable governments, may present the risks of nationalization of businesses, restrictions on foreign ownership and prohibitions on the repatriation of assets, and may have less protection of property rights than more developed countries. The economies of countries with emerging markets may be based on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates. Local securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times.

§ The securities are not directly exposed to fluctuations in foreign exchange rates with respect to the SX5E Index. The value of your securities will not be adjusted for exchange rate fluctuations between the U.S. dollar and the currencies upon which the equity securities included in the SX5E Index are based, although any currency fluctuations could affect the performance of the SX5E Index. Therefore, if the applicable currencies appreciate or depreciate relative to the U.S. dollar over the term of the securities, you will not receive any additional payment or incur any reduction in any payment on the securities.

§ The securities are subject to currency exchange risk with respect to the MXEF Index. Because the prices of the equity securities included in the MXEF Index are converted into U.S. dollars for the purposes of calculating the level of the MXEF Index, holders of the securities will be exposed to currency exchange rate risk with respect to the currencies in which securities included in the MXEF Index are traded. Your net exposure will depend on the extent to

June 2015 Page 10

Contingent Income Auto-Callable Securities due June 16, 2022

Based on the Worst Performing of the Russell 2000^® Index, the EURO STOXX 50^® Index and the MSCI Emerging Markets Index
Principal at Risk Securities

which the currencies in which securities included in the MXEF Index are traded strengthen or weaken against the U.S. dollar. If the U.S. dollar strengthens against the currencies in which securities included in the MXEF Index are traded, the levels of the MXEF Index will be adversely affected and any payment on the securities may be reduced. Of particular importance to potential currency exchange risk are:

o existing and expected rates of inflation;

o existing and expected interest rate levels;

o the balance of payments in the countries issuing those currencies and the United States and between each country and its major trading partners;

o political, civil or military unrest in the countries issuing those currencies and the United States; and

o the extent of government surpluses or deficits in the countries issuing those currencies and the United States.

All of these factors are in turn sensitive to the monetary, fiscal and trade policies pursued by the governments of the countries issuing those currencies and the United States and other countries important to international trade and finance.

§ Early redemption risk.The term of your investment in the securities may be limited to as short as approximately three months by the automatic early redemption feature of the securities. If the securities are redeemed prior to maturity, you will receive no more contingent quarterly payments and may be forced to reinvest in a lower interest rate environment and may not be able to reinvest the proceeds from an investment in the securities at a comparable return for a similar level of risk.

§ Economic interests of the issuer, the calculation agent, the agent of the offering of the securities and other affiliates of the issuer may be different from those of investors. We and our affiliates play a variety of roles in connection with the issuance of the securities, including acting as calculation agent and as an agent of the offering of the securities, hedging our obligations under the securities and making the assumptions used to determine the pricing of the securities and the estimated value of the securities, which we refer to as JPMS’s estimated value. In performing these duties, our economic interests and the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the securities. The calculation agent has determined the initial index values, the coupon barrier levels and the downside threshold levels and will determine the final index values and whether the closing value of each underlying index on any determination date is greater than or equal to its initial index value or is below its coupon barrier level or downside threshold level, as applicable. Determinations made by the calculation agent, including with respect to the occurrence or non-occurrence of market disruption events, may affect the payment to you at maturity or whether the securities are redeemed early. In addition, our business activities, including hedging and trading activities, could cause our economic interests to be adverse to yours and could adversely affect any payment on the securities and the value of the securities. It is possible that hedging or trading activities of ours or our affiliates in connection with the securities could result in substantial returns for us or our affiliates while the value of the securities declines. Please refer to “Risk Factors — Risks Relating to Conflicts of Interest” in the accompanying product supplement no. 4a-I for additional information about these risks.

§ JPMS’s estimated value of the securities is lower than the original issue price (price to public) of the securities. JPMS’s estimated value is only an estimate using several factors. The original issue price of the securities exceeds JPMS’s estimated value because costs associated with selling, structuring and hedging the securities are included in the original issue price of the securities. These costs include the selling commissions, the structuring fee, the projected profits, if any, that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the securities and the estimated cost of hedging our obligations under the securities. See “Additional Information about the Securities — JPMS’s estimated value of the securities” in this document.

§ JPMS’s estimated value does not represent future values of the securities and may differ from others’ estimates. JPMS’s estimated value of the securities is determined by reference to JPMS’s internal pricing models. This estimated value is based on market conditions and other relevant factors existing at the time of pricing and JPMS’s assumptions about market parameters, which can include volatility, dividend rates, interest rates and other factors. Different pricing models and assumptions could provide valuations for securities that are greater than or less than JPMS’s estimated value. In addition, market conditions and other relevant factors in the future may change, and any assumptions may prove to be incorrect. On future dates, the value of the securities could change significantly based on, among other things, changes in market conditions, our creditworthiness, interest rate movements and other relevant factors, which may impact the price, if any, at which JPMS would be willing to buy

June 2015 Page 11

Principal at Risk Securities

securities from you in secondary market transactions. See “Additional Information about the Securities — JPMS’s estimated value of the securities” in this document.

§ JPMS’s estimated value is not determined by reference to credit spreads for our conventional fixed-rate debt. The internal funding rate used in the determination of JPMS’s estimated value generally represents a discount from the credit spreads for our conventional fixed-rate debt. The discount is based on, among other things, our view of the funding value of the securities as well as the higher issuance, operational and ongoing liability management costs of the securities in comparison to those costs for our conventional fixed-rate debt. If JPMS were to use the interest rate implied by our conventional fixed-rate credit spreads, we would expect the economic terms of the securities to be more favorable to you. In addition, JPMS’s estimated value might be lower if it were based on the interest rate implied by our conventional fixed-rate credit spreads. Consequently, our use of an internal funding rate would have an adverse effect on the terms of the securities and any secondary market prices of the securities. See “Additional Information about the Securities — JPMS’s estimated value of the securities” in this document.

§ The value of the securities as published by JPMS (and which may be reflected on customer account statements) may be higher than JPMS’s then-current estimated value of the securities for a limited time period. We generally expect that some of the costs included in the original issue price of the securities will be partially paid back to you in connection with any repurchases of your securities by JPMS in an amount that will decline to zero over an initial predetermined period. These costs can include selling commissions, the structuring fee, projected hedging profits, if any, and, in some circumstances, estimated hedging costs and our secondary market credit spreads for structured debt issuances. See “Additional Information about the Securities — Secondary market prices of the securities” in this document for additional information relating to this initial period. Accordingly, the estimated value of your securities during this initial period may be lower than the value of the securities as published by JPMS (and which may be shown on your customer account statements).

§ Secondary market prices of the securities will likely be lower than the original issue price of the securities. Any secondary market prices of the securities will likely be lower than the original issue price of the securities because, among other things, secondary market prices take into account our secondary market credit spreads for structured debt issuances and, also, because secondary market prices (a) exclude selling commissions and the structuring fee and (b) may exclude projected hedging profits, if any, and estimated hedging costs that are included in the original issue price of the securities. As a result, the price, if any, at which JPMS will be willing to buy securities from you in secondary market transactions, if at all, is likely to be lower than the original issue price. Any sale by you prior to the maturity date could result in a substantial loss to you. See the immediately following risk factor for information about additional factors that will impact any secondary market prices of the securities.

The securities are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your securities to maturity. See “— Secondary trading may be limited” below.

§ Secondary market prices of the securities will be impacted by many economic and market factors.  The secondary market price of the securities during their term will be impacted by a number of economic and market factors, which may either offset or magnify each other, aside from the selling commissions, structuring fee, projected hedging profits, if any, estimated hedging costs and the closing level of each underlying index, including:

o any actual or potential change in our creditworthiness or credit spreads;

o customary bid-ask spreads for similarly sized trades;

o secondary market credit spreads for structured debt issuances;

o the actual and expected volatility in the closing level of each underlying index;

o the time to maturity of the securities;

o whether the closing level of any underlying index has been, or is expected to be, less than its coupon barrier level on any determination date and whether the final index value of any underlying index is expected to be less than its downside threshold level;

o the likelihood of an early redemption being triggered;

o the dividend rates on the equity securities included in the underlying indices;

o the actual and expected positive or negative correlation between the underlying indices, or the actual or expected absence of any such correlation;

o interest and yield rates in the market generally;

June 2015 Page 12

Contingent Income Auto-Callable Securities due June 16, 2022

Based on the Worst Performing of the Russell 2000^® Index, the EURO STOXX 50^® Index and the MSCI Emerging Markets Index
Principal at Risk Securities

o the exchange rates and the volatility of the exchange rates between the U.S. dollar and each of the currencies in which the equity securities included in the SX5E Index and the MXEF Index trade and the correlation among those rates and the levels of the SX5E Index and the MXEF Index; and

o a variety of other economic, financial, political, regulatory and judicial events.

Additionally, independent pricing vendors and/or third party broker-dealers may publish a price for the securities, which may also be reflected on customer account statements. This price may be different (higher or lower) than the price of the securities, if any, at which JPMS may be willing to purchase your securities in the secondary market.

§ Hedging and trading activities by the issuer and its affiliates could potentially affect the value of the securities. The hedging or trading activities of the issuer’s affiliates and of any other hedging counterparty with respect to the securities on or prior to the pricing date and prior to maturity could have adversely affected, and may continue to adversely affect, the closing levels of the underlying indices. Any of these hedging or trading activities on or prior to the pricing date could have affected the initial index values and, as a result, the coupon barrier levels, which are the respective levels at or above which the underlying indices must close on each determination date in order for you to earn a contingent quarterly payment or, if the securities are not called prior to maturity, the downside threshold levels, which are the respective levels at or above which the underlying indices must close on the final determination date in order for you to avoid being exposed to the negative price performance of the worst performing underlying index at maturity. Additionally, these hedging or trading activities during the term of the securities could potentially affect the values of the underlying indices on the determination dates and, accordingly, whether the securities are automatically called prior to maturity and, if the securities are not called prior to maturity, the payment to you at maturity. It is possible that these hedging or trading activities could result in substantial returns for us or our affiliates while the value of the securities declines.

§ Secondary trading may be limited. The securities will not be listed on a securities exchange. There may be little or no secondary market for the securities. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the securities easily. JPMS may act as a market maker for the securities, but is not required to do so. Because we do not expect that other market makers will participate significantly in the secondary market for the securities, the price at which you may be able to trade your securities is likely to depend on the price, if any, at which JPMS is willing to buy the securities. If at any time JPMS or another agent does not act as a market maker, it is likely that there would be little or no secondary market for the securities.

§ The U.S. federal income tax consequences of an investment in the securities are uncertain. There is no direct legal authority as to the proper U.S. federal income tax treatment of the securities, and we do not intend to request a ruling from the IRS. The IRS might not accept, and a court might not uphold, the treatment of the securities as prepaid forward contracts with associated contingent coupons, as described in “Additional Information about the Securities — Additional Provisions — Tax considerations” in this document and in “Material U.S. Federal Income Tax Consequences” in the accompanying product supplement no. 4a-I. If the IRS were successful in asserting an alternative treatment for the securities, the timing and character of any income or loss on the securities could be materially affected. Although the U.S. federal income tax treatment of contingent quarterly payments (including any contingent quarterly payments paid in connection with an early redemption or at maturity) is uncertain, in determining our reporting responsibilities we intend (in the absence of an administrative determination or judicial ruling to the contrary) to treat any contingent quarterly payments as ordinary income. In addition, in 2007 Treasury and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. The notice focuses in particular on whether to require investors in these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments and the relevance of factors such as the nature of the underlying property to which the instruments are linked. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially affect the tax consequences of an investment in the securities, possibly with retroactive effect. You should review carefully the section entitled “Material U.S. Federal Income Tax Consequences” in the accompanying product supplement no. 4a-I and consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments and the issues presented by this notice.

Non-U.S. Holders — Tax Consideration. The U.S. federal income tax treatment of contingent quarterly payments is uncertain, and although we believe it is reasonable to take a position that contingent quarterly payments are not subject to U.S. withholding tax (at least if an applicable Form W-8 is provided), a withholding agent may nonetheless withhold on these payments (generally at a rate of 30%, subject to the possible reduction of that rate under an applicable income tax treaty), unless income from your securities is effectively connected with your conduct of a trade

or business in the United States (and, if an applicable treaty so requires, attributable to a permanent establishment in the United States). In the event of any withholding, we will not be required to pay any additional amounts with respect to amounts so withheld. If you are not a United States person, you are urged to consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the securities in light of your particular circumstances.

Russell 2000^® Index Overview

The Russell 2000^® Index consists of the middle 2,000 companies included in the Russell 3000E^TM Index and, as a result of the index calculation methodology, consists of the smallest 2,000 companies included in the Russell 3000^® Index. The Russell 2000^® Index is designed to track the performance of the small capitalization segment of the U.S. equity market. For additional information on the Russell 2000^® Index, see the information set forth under “Equity Index Descriptions — The Russell Indices” in the accompanying underlying supplement no.1a-I.

MSCI Emerging Markets Index Overview

The MSCI Emerging Markets Index is a free-float adjusted market capitalization index that is designed to measure equity market performance of global emerging markets. As of the date of this document, the MSCI Emerging Markets Index consists of the following 23 emerging market country indices: Brazil, Chile, China, Colombia, Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Korea, Malaysia, Mexico, Peru, Philippines, Poland, Qatar, Russia, South Africa, Taiwan, Thailand, Turkey and United Arab Emirates.

Information as of market close on June 12, 2015:

Bloomberg Ticker Symbol:	MXEF	52 Week High (on 9/3/2014):	1,100.98
Current Closing Level:	979.46	52 Week Low (on 12/16/2014):	909.98
52 Weeks Ago (on 6/12/2014):	1,054.74

The following table sets forth the published high and low closing levels, as well as end-of-quarter closing levels, of the MSCI Emerging Markets Index for each quarter in the period from January 1, 2010 through June 12, 2015. The graph following the table sets forth the daily closing levels of the MSCI Emerging Markets Index during the same period. The closing level of the MSCI Emerging Markets Index on June 12, 2015 was 979.46. We obtained the closing level information above and the information in the table and graph below from Bloomberg, without independent verification. The historical levels of the MSCI Emerging Markets Index should not be taken as an indication of future performance, and no assurance can be given as to the closing level of the MSCI Emerging Markets Index on the valuation date. The payment of dividends on the stocks that constitute the MSCI Emerging Markets Index are not reflected in its closing level and, therefore, have no effect on the calculation of the payment at maturity.

Additional Information about the Securities

Please read this information in conjunction with the summary terms on the front cover of this document.

Additional Provisions
Record date:	The record date for each contingent payment date is the date one business day prior to that contingent payment date.
Postponement of maturity date:	If the scheduled maturity date is not a business day, then the maturity date will be the following business day.  If the scheduled final determination date is not a trading day or if a market disruption event occurs on that day so that the final determination date is postponed and falls less than three business days prior to the scheduled maturity date, the maturity date of the securities will be postponed to the third business day following that final determination date as postponed.
Minimum ticketing size:	$1,000 / 100 securities
Trustee:	Deutsche Bank Trust Company Americas (formerly Bankers Trust Company)
Calculation agent:	JPMS
JPMS’s estimated value of the securities:	JPMS’s estimated value of the securities set forth on the cover of this document is equal to the sum of the values of the following hypothetical components: (1) a fixed-income debt component with the same maturity as the securities, valued using our internal funding rate for structured debt described below, and (2) the derivative or derivatives underlying the economic terms of the securities. JPMS’s estimated value does not represent a minimum price at which JPMS would be willing to buy your securities in any secondary market (if any exists) at any time. The internal funding rate used in the determination of JPMS’s estimated value generally represents a discount from the credit spreads for our conventional fixed-rate debt. For additional information, see “Risk Factors — JPMS’s estimated value is not determined by reference to credit spreads for our conventional fixed-rate debt.” The value of the derivative or derivatives underlying the economic terms of the securities is derived from JPMS’s internal pricing models. These models are dependent on inputs such as the traded market prices of comparable derivative instruments and on various other inputs, some of which are market-observable, and which can include volatility, dividend rates, interest rates and other factors, as well as assumptions about future market events and/or environments. Accordingly, JPMS’s estimated value of the securities on the pricing date is based on market conditions and other relevant factors and assumptions existing at that time. See “Risk Factors — JPMS’s estimated value does not represent future values of the securities and may differ from others’ estimates.” JPMS’s estimated value of the securities is lower than the original issue price of the securities because costs associated with selling, structuring and hedging the securities are included in the original issue price of the securities. These costs include the selling commissions paid to JPMS and other affiliated or unaffiliated dealers, the structuring fee, the projected profits, if any, that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the securities and the estimated cost of hedging our obligations under the securities. Because hedging our obligations entails risk and may be influenced by market forces beyond our control, this hedging may result in a profit that is more or less than expected, or it may result in a loss. We or one or more of our affiliates will retain any profits realized in hedging our obligations under the securities. See “Risk Factors — JPMS’s estimated value of the securities is lower than the original issue price (price to public) of the securities” in this document.
Secondary market prices of the securities:	For information about factors that will impact any secondary market prices of the securities, see “Risk Factors — Secondary market prices of the securities will be impacted by many economic and market factors” in this document. In addition, we generally expect that some of the costs included in the original issue price of the securities will be partially paid back to you in connection with any repurchases of your securities by JPMS in an amount that will decline to zero over an initial predetermined period that is intended to be the shorter of six months and one-half of the stated term of the securities.  The length of any such initial period reflects the structure of the securities, whether our affiliates expect to earn a profit in connection with our hedging activities, the estimated costs of hedging the securities and when these costs are incurred, as determined by JPMS.  See “Risk Factors — The value of the securities as published by JPMS (and which may be reflected on customer account statements) may be higher than JPMS’s then-current estimated value of the securities for a limited time period.”

Tax considerations: You should review carefully the section entitled “Material U.S. Federal Income Tax Consequences” in the accompanying product supplement no. 4a-I. In determining our reporting responsibilities we intend to treat (i) the securities for U.S. federal income tax purposes as prepaid forward contracts with associated contingent coupons and (ii) any contingent quarterly payments as ordinary income, as described in the section entitled “Material U.S. Federal Income Tax Consequences — Tax Consequences to U.S. Holders — Notes Treated as Prepaid Forward Contracts with Associated Contingent Coupons” in the accompanying product supplement no. 4a-I. Based on the advice of Davis Polk & Wardwell LLP, our special tax counsel, we believe that this is a reasonable treatment, but that

Contingent Income Auto-Callable Securities due June 16, 2022

Based on the Worst Performing of the Russell 2000^® Index, the EURO STOXX 50^® Index and the MSCI Emerging Markets Index
Principal at Risk Securities

there are other reasonable treatments that the IRS or a court may adopt, in which case the timing and character of any income or loss on the securities could be materially affected. In addition, in 2007 Treasury and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. The notice focuses in particular on whether to require investors in these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments and the relevance of factors such as the nature of the underlying property to which the instruments are linked. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially affect the tax consequences of an investment in the securities, possibly with retroactive effect. You should consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments and the issues presented by this notice.

Non-U.S. Holders — Tax Considerations. The U.S. federal income tax treatment of contingent quarterly payments is uncertain, and although we believe it is reasonable to take a position that contingent quarterly payments are not subject to U.S. withholding tax (at least if an applicable Form W-8 is provided), a withholding agent may nonetheless withhold on these payments (generally at a rate of 30%, subject to the possible reduction of that rate under an applicable income tax treaty), unless income from your securities is effectively connected with your conduct of a trade or business in the United States (and, if an applicable treaty so requires, attributable to a permanent establishment in the United States). If you are not a United States person, you are urged to consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the securities in light of your particular circumstances.

FATCA. Withholding under legislation commonly referred to as “FATCA” could apply to payments on the securities, and (if they are recharacterized, in whole or in part, as debt instruments) could also apply to the payment of gross proceeds of a sale of a security occurring after December 31, 2016 (including an early redemption or redemption at maturity). You should consult your tax adviser regarding the potential application of FATCA to the securities.

In the event of any withholding on the securities, we will not be required to pay any additional amounts with respect to amounts so withheld.

Supplemental use of proceeds and hedging:	The securities are offered to meet investor demand for products that reflect the risk-return profile and market exposure provided by the securities. See “How the Securities Work” in this document for an illustration of the risk-return profile of the securities and “Russell 2000® Index Overview,” “EURO STOXX 50® Index Overview” and “MSCI Emerging Markets Index Overview” in this document for a description of the market exposure provided by the securities. The original issue price of the securities is equal to JPMS’s estimated value of the securities plus the selling commissions paid to JPMS and other affiliated or unaffiliated dealers and the structuring fee, plus (minus) the projected profits (losses) that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the securities, plus the estimated cost of hedging our obligations under the securities.
Benefit plan investor considerations:	See “Benefit Plan Investor Considerations” in the accompanying product supplement no. 4a-I
Supplemental plan of distribution:	Subject to regulatory constraints, JPMS intends to use its reasonable efforts to offer to purchase the securities in the secondary market, but is not required to do so. JPMS, acting as agent for JPMorgan Chase & Co., will pay all of the selling commissions it receives from us to Morgan Stanley Wealth Management. In addition, Morgan Stanley Wealth Management will receive a structuring fee as set forth on the cover of this document for each security. We or our affiliate may enter into swap agreements or related hedge transactions with one of our other affiliates or unaffiliated counterparties in connection with the sale of the securities and JPMS and/or an affiliate may earn additional income as a result of payments pursuant to the swap or related hedge transactions. See “— Supplemental use of proceeds and hedging” above and “Use of Proceeds and Hedging” on page PS-42 of the accompanying product supplement no. 4a-I.

Validity of the securities: In the opinion of Davis Polk & Wardwell LLP, as our special products counsel, when the securities offered by this pricing supplement have been executed and issued by us and authenticated by the trustee pursuant to the indenture, and delivered against payment as contemplated herein, such securities will be our valid and binding obligations, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability (including, without limitation, concepts of good faith, fair dealing and the lack of bad faith), provided that such counsel expresses no opinion as to the effect of fraudulent conveyance, fraudulent transfer or similar provision of applicable law on the conclusions expressed above.  This opinion is given as of the date hereof and is limited to the federal laws of the United States of America, the laws of the State of New York and the General Corporation Law of the State of Delaware.  In addition, this opinion is subject to customary assumptions about the trustee’s authorization, execution and delivery of the indenture and its authentication of the securities and the validity, binding nature and enforceability of the indenture with respect to the trustee, all as stated in the letter of such counsel dated November 7, 2014, which was
